SPECIFICATION forming part of Letters Patent No. 359,002, dated March 8, 1887.

Application filed March 15, 1886.

To all whom it may concern:

Be it known that I, MIFFLIN \VOODWARD BAILY, of Pottstown, in the county of Montgomery and State of Pennsylvania, have in vented a new and Improved Heat-Regulator, of which the following is a full, clear, and exact description.

My invention relates to the construction of a heat-regulating apparatus, the object of the invention being to provide a means whereby the draft of the furnace may be regulated from the apartment within which the heat is delivered, and whereby,whe'n less heat is required in the apartment, the draft of the furnace may be checked, and, conversely,when more heat is required in the apartment, the draft of the furnace may be adjusted so that the fires will burn freely.

The invention consists in a register provided with two openings controlled by a valve and adapted for connection by pipes with the smoke-pipe and ash-pit of a furnace, as will be hereinafter more particularly set forth.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a face view of my improved heatregulating attachment, the grating, however, being removed and certain portions of the apparatus being shown in section. Fig. 2 is a sectional plan view of the apparatus,taken on line at m of Fig. 1; and Fig. 3 is a diagram illustrating the relative arrangement of the furnace and regulator.

In the drawings above referred to, A represents a circular casing that is in communication with the smoke-pipe of the furnace through the medium of the flue or tubeB and with the ash-pit beneath the fire-box of said furnace through the medium of the flue or tube O,the openings 13 O to the two lines being controlled by a valveplate, D, that is mounted on one end of a lever, E, the opposite end of the lever being provided with a knob, e. Thelever Eis mounted upon a central shaft, F, that is supported in two bearings, a a, the bearing abeing fixed to the rear wall of the chamber A, while the bearing a is carried by a crossbar, G, arranged across the face of the chamber, as shown, the parts being so proportioned that Serial No. 195,270. No model.)

by turning the lever Ethe valveplate maybe moved to open or close the way to either of the fines B 0.

Referring now more particularly to Fig. 3, it will be seen that the line B, as abovestated, leads to the smokestack I of the furnace H, and it will be readily understood that when air is admitted to said smoke-stack through the open front of casing A and the flue B the draft of the furnace will be checked. It will also be seen that the flue G leads into the ashpit of the furnace,so as to deliver air beneath the grate J, so that when the valve-plate D is moved from the front of the opening to the flue O the fire will burn freely, the valve be ing so arranged that when removed from in front of the opening to the flue O the opening to the flue B will be completely closed.

From the arrangement described it will be seen that the draft of the furnace may be regulated, as desired, from the apartment within which the heat is delivered; but,-in order that the draft may be regulated from a position close to the furnace as well as from the apartment, I have provided the shaft F with apulley, K, about which there is passed a cord or chain, L, which passes over she ves c a, mounted as shown best in Fig. 1, and finally over a sheave, M, thatis provided with a crank-arm, N, the construction being such that by simply .turning the crank-arm the valve-plate D may be thrown to a position to regulate the draft, it being understood, of course, that the said valve-plate might be moved to an intermediate position, so as to admit air through both lines B G at the same time.

The apparatus described not only serves to perfectly regulate the draft of the furnace,but also acts to thoroughly ventilate the apartment from which the fines B and 0 lead.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The regulator for furnaces herein shown and described, consisting of a casing open at one side and having peripheral openings, and a valve mechanism for opening or closing said openings, substantially as set forth.

2. The casing A, having adjacent peripheral openings B O, shaft F, arm E, and valve D, concentric with the periphery of the casing and closing one Opening or partially closing tiguous, and of a valve for cont-rolling said 7 both, according to its adjusted position, substantially as shown and described.

3. The combination,with the casing A. having Openings B G, shaft F, arm E, and valve D, of the pulley K on shaft F, pulley M,chain L,and guide-sheaves c c, substantially as shown and described.

4. The combination, with the smoke-pipe and ash-pit of a furnace, of a register having two peripheral openings controlled bya valve, and pipes connecting said register with the furnace,substantially as shown and described.

5. The combination,with afurnace, of aflue extending to the apartment to be heated from the ash-box of said furnace, and a flue extending from the smoke-pipe of the furnace to said apartment-,the openings ofsaid fiues being conopenings,substantially as shown and described. 6. The combination, with the smoke-outlet and the ash -box of a furnace, of H ues connected at their inner ends with said smoke-outlet and v K, c c, and M, and a chain, L, substantially as 30 described.
